SPECIFICATION forming part of Letters Patent No. 412,430, dated October 8, 1889.

Application filed .Tune 14, 1889.

To aZZ wil/0m it may concern:

Be it known that I, ALLEN SWAB, a citizen ville, in the county of Dauphin and State of Pennsylvania,have invented certain new and useful Improvements in Window-Casings; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art .to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of'reference marked thereon, which forni a part of this specication.

This invention relates to windows, and has for its object to provide a simple, compact, and eflicient construction, whereby the sash can be removed at will for any purpose, as repairing, cleaning, painting, &c., or be held at any desired point, either open or closed, or any intermediate position.

The improvement consists in ak movable section at the side of the window-casing and peculiar and novel devices for operating the same. The said movable section can be hinged at either edge, or may be constructed to move bodily, always remaining parallel toits normal position. However, no claim is made, broadly, to the movable section, but to the means and devices for operating the same.

The improvement further consists in the parts, which will be hereinafter more fully described and claimed, and which are shown in the annexed drawings, in which- Figure 1 is a front view of a window embodying my invention. Fig. 2 is a cross-section of one side of the window on the line X X of Fig. l. Fig. 3 is a vertical section vofone side of the window on the line Y Y of Fig. 2. Fig. 4 is an enlarged detail view of the sliding bar and the toothed cam-segment for operating the same. Fig. 5 is aview similar to Fig. 4, showing a different .position of the parts. Fig. 6 is a cross-section of the win dow on the line Z Z of Fig. 1, showing the operation of the same by dotted lines.

The windowcasingA and the sliding sashes B and C are of welLknown construction -and relative arrangement. The jambs have the usual rabbets or vertical ways b and b for Serial No. 314,262. (No model.)

t-he sashes to slide in. movable, and for convenience the right-hand jamb is shown as being movable and composed of two independent sections D and E, each being operated by precisely the same means. The sliding bar F, held to the section by the keepers I, is provided with a series of cam-heads f, which act in opposition to a fixed board J to move the said section out against the sash, and with a toothed in- Cline G, which comes opposite the ,toothed segment K, that is mounted on the shaft L. ,This segment is cut away t0 form the rear curved edge 10,'whicl1 is eccentric to the shaft L and which is adapted to engage with thekeeper H, fastened to the section to draw the said section in and away from the sash when the said segment is turned up, The cams f and the segment G are shearcd off on one side to prevent binding when operating the section. The shaft L is journaled in the board J and is provided at its outer end with a suitable handle Z for rotating it. To move the section ont to hold the sash the shaft L is rotated, so that the segment K will move the bar F down, thus forcing the cams f between the board J and the said section, and to draw the section away from the sash the shaft L is turned in the opposite direction, so that the cam-edge lo of the segment K will draw in on the keeper H and carry the said section in.

The board J is a fixed part of the frame and is grooved at j to receive the bar F, and mortised at j to give clearance for the cams When the section is drawn close to the board or jamb J, the bar F enters the groove j, thereby economizing space.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. The combination, with a window-casing having a movable section and the sliding sash, of the sliding bar having cams f-placed between the said section and a fixed part of the casing, the keeper H, the shaft, and the segment on the shaft, substantially as described.

2. The combination, with the window-casing having a movable sect-ion for the purpose described and having a board J, of the bar F, having cams f, and the toothed incline G of Either jamb may be IOO the shaft and the correspondingly-toothed segment K on the said shaft, substantially as set forth.

3. The combination, with the window-casing having a movable section D and a board J, of the keeper H, secured to section D, the shaft L, and the cam K on shaft L, adapted to move Section D out and having the eamedge lo, which acts on the keeper H and draws the said section D back, substantially as set forth.

4. In aWindow-casing, the con1bination,with the movable section and the board J, of the bar F, having cams f, and a toothed incline G, the keeper H, and the shaft having` a toothed
